The POSEIDON study is a multi-center, prospective, single arm, crossover pivotal study enrolling up to 70 pivotal cohort patients and up to 45 additional Roll-in patients with refractory or recurrent ascites at up to 20 sites. Pivotal cohort patients will undergo a 3-month pre-implant observation phase after enrollment, followed by implantation of the alfapump and 24 months of post-implant follow up. An analysis will be conducted to support an application for device approval when a minimum of 40 treated pivotal cohort patients are through 6 months.
